Hello Jose, And thank you very much for the information. The tang does extend through the hilt and as far as the horn on the hilt goes, it is very light in color but not as light as some that I have seen and have on other items. I thought it might be albino carabao horn but wasn't quite sure until you made your comment about it. One of the things that impressed me about this was how well that it had been taken care of, except for the scabbard.
The ones that I normally find are almost always covered in rust and the blades are usually bent and pretty well beaten up. I would guess that this must have been a valued keepsake to the owner. Thank you again.
Robert
